Don't.
The story:
Today I had to go down to the computer store and buy a fax machine. The computer store is more than a mile away and I had to walk there. This is southern California, so it was around 95 today... Needless to say walking uphill for a mile in 95 degree heat while carrying a 25 lbs fax machine is a tiring feat. When I got home I wanted something to drink but we were out of bottled water. However, yesterday I was at walmart and got a four-pack of full throttle as they were completely out of monster and the only thing they had that wasn't redbull was in four-packs. This energy drink had been sitting in my heated room however, so it wasn't exactly cooling. Do you know what is cooling though? Ice cream. Extra-vanilla ice cream. At this point I had already opened the energy drink and didn't want to waste it, then I got an idea. If they put coke or rootbeer in ice cream to make rootbeer floats, why couldn't I do it with an energy drink. Well I now know why. Citrus energy drink + Double Vanillabean ice cream don't exactly taste charming together... Maybe if I had tried that crappy cherry flavored Amp with ice cream it would work better, but for now, I leave you with this tidbit of knowledge. Energy drink floats are not good.
